Mature Water Flood Analysis (MWFA)

Mature Water Flood Analysis is a workflow for identifying the performance gaps in the mature waterfloods performance.

Mature Water Flood Analysis is applied to the Reservoirs.

MWFA

As a result Mature Water Flood Analysis generates Blocks/Patterns Enhancement List.

Block Enhancement List

Workflow

  1. Upload the required data
  2. Gridding - Divide the field into Patterns/Blocks/Buckets
  3. Calculate STOIIP for each reservoir using blocks
  4. Match STOIIP to official numbers by changing the edge Blocks areas
  5. Make Plots (by field, by reservoir, by block):History, RF vs HCPVinj, RF vs well spacing, WOR vs Np, VRR vs t
  6. Make Maps (by reservoir) showing Blocks: HCPV, HCPVinj, RF, VRR
  7. Make Cross sections
  8. Calculate Blocks Enhancement List
  9. Create Action List
  10. Execute


Repeat steps 5-6-7-8-9-10 routinely (monthly, quarterly, half year).

1. Data Required

9. Action List

The typical actions are:

  • Convert producing well to injector
  • Increase/Decrease injection well rate
  • Add/squeeze Perforations
  • Drill production/injection well
